Be it known that `l. HAnoLo l. S'r.\GE,-a citizen of the United States, and a resident ot' San Francisco. county of San Francisco, 5 Stateol *(alitorn-ia, have invented a certain Shoveling and Loading Machine, of which the tollowingis a specification. accompanied h v drawings;

This invention relates to Shoveling and ore, coal and other broken materials into a suitable car. i A

The object of the invention is to enable a car or cars running on rails to remain in. a given position eitheron -the surface ogin a mine, hut permit the car or ears to Vheloaded hy a shoveling vand loading machine in the form of a unit transportable under itsI own power and capable of traveling in any direction and carrying `the material in a hopper from distant points to the ear orears. Another ohject of the invention is to secure suitahle means `-in the form of a conveying element into which material dumped and from thence conveyed into the ('ll's.

'lhe invention is Shown in one of its prei'erred forms in the accompanying drawings. in which-fr Figure l is a .side elevation of a complete unit comprising a conveyor element and a iuovahie and transportable shove-ling and loadingr element.

Figure 2 is an enlarged side elevation of the shoveling and loading element'.

Figure G is a top plan view partly hroken away of the conveying element.

Figure 7 is a side elevation of a moditicd form of the Shoveling and loading unit.

Figure 8 is a longitudinal sectional elevation ot the modified form ot the shoveling and loading unit Shown in Figure 7, and

Figure S), iS a top plan view of Figure 8. Referring to the drawings, a portion of a hopper ear A to he loaded, is shown adapted to travel on the rails B and a Shoveling and loading unit. C capable of being driven upon loading machine tor shoveling and loadingv away ot the shoveling and loading clementx the ground or over the. floorv of the mine under its own power, shovels and loads the material into the hopper D of a conveying element .E adapted to be located.intermediatethe point of delivery of the Shoveling and loading unit,l and the hopperl car rohe loaded.

The'conveyingY element may he of any -Q being mounted on the frame and having a worm li meshing with the worm wheel S on the shaft T, supported in suitahle hearings and extending outwardly beyond the conveyor trame and operatively connected to a vertical shaft ll having a hevel gear V. driving a counter-'shaft X having a bevel gear lV. which countershaf t is also provided with a bevel gear Y meshing with a hevel gear-'Z on the upper sprocketv shatt- .l hy means of which driving mechanism the conveyor is actuated.' .\n electric controller l may he conveniently mounted On the upright (l and current. is supplied to the motor through a SuitahleA fiexihle cahle'b and connections n and r. Any other suitable operat-ive connections may be provided between the motor and the conveyor.

The shoveling and loading element in the torm..of ascii-contained nnitcomprises the trame c. on which is mounted a suitable motor preferably an electric motor, `for operating a Scoop or shovel g and for fur nishing power for driving the element itself. Driving wheels having tractor Surfaces are mounted on the rear axle 'j of the Shoveling element` and a single front Supporting and steering wheel 7c is mounted on the front. axle o. Front and rear sprocket shafts p and q are suitably mounted on the frame of the shoveling unit, and front and rear sprockets' r vland s are carried by Said Spreek; A et `Shafts over which sprocketl chains t are connected.

sition indicated in Figure As' the chainsv are driven rearwardly, the scoop or shovel picks up the material and travels upwardly with the conveyor chains and as the shovel rises, the arms u are rocked on the pivot fw until the roller y lies upon the chains.-v As the shovel continues upwardly, the guide roller v/ enters beneath the grooved guide 3 at the rearward end ofthe shoveling unit, and is guided rearwardly and downwardly, thus carrying the scoop or shovel into dump'- ing position as indicated in Figures 1 and 2, the guide roller g/ comingT to rest at the stop l formed at the lower end of the grooved guide 3 and after the material is dumped, the direction of movement of. the chainspis reversed and the shovel is carried downwardly to digging position, indicated in Figure lWith the shovel or scoop in the position ot' Figure 3, the lip of the scoop is 'forced into the material' by driving the whole machine forward.

Any suitable driving connections may be provided between the motorA f and the wheel Il. ot the shoveling element, and between the motor and the chains. ln Figures 3 and 4, coi'nhined electric and fluid pressure driving connections are shown. A. pinion on the motor shaft meshes with a gear (i lwhich drives any suitable rotary pump 7 for pumpin.;r oil or other fluid `roui a tank 8 through I the supply pipe 7a and outtlu'ough the pipe 8f? which branches and leads through suitable "valves 9 and 10 to suitable rotary gear motors 11 and 12. One motor 11 operates the driving wheels ol" the unit and the other motor 12 operates the conveyor chains. The pipe- 13 connectsv 'from the pipe 8" to the valve 9 and from thence the pipes 1l and 15 lead to the gear motor 11 forming the Supply and outlet from said motor. Each valve 9 and 10 is a threesway valve and the pipe 1G leads from the valve 9 to a pipe 17, which connects with the tank 8 for the rcturn ot' fluid.

A pipe 18 leads from the pipe 8a on the main pump to a` connection 19 from which one branch 2O connects with a three-way valve 10 and from this valve the pipes 21 and 22 connect with the casing ot the gear pump 12. Another pipe .23 leads from the valve lo to the pipe 16 Aforming a return from the pump 12. A spring actuated valve 24 is preferably inserted in the connection between the pipe 18 and the pipe 17.

Onelof the rotary gears 25 of the gear pump 11 is provided with a pinion 2.5 meshing with a gear 26 on a counter shaft 2Gz having a gear 26", which in turn mesnes with an internal gear 27 on one of the driving Wheels h. One of the gears 28 of the gear pump 12 is operatively connected by the gear 281 to a gear 29 on the rear sprocket shaft g for driving the sprocket chainsof the scoop. f

The controlling valves 9 and 10 may be conveniently manipulated by the levers 3() and 31, on the outside of the frame of the machine. The lever 30 is connected by the chain 32 and suitable sprockets to the valve 9 and the leve-r 31 on the shaft 33 is connect ed directly to operate the valve 10.

In the position ot the valves `9 and 10 shown in Figure 3, pressure fluid is supplied to the gear motors 11 and 12, and returns from both motors through the valve casing and back through the pipes to the tank 8. Obviously, the motive luid fdr either one or both of the/motors may be shut off Without stopping the main pump 7, by turning the valves to proper positions, so .that the -iiuid lay-passes the motors 1,1 and 12 and returns through the pipes 18 and 17 and the remaining connections to the tank 8. Suitable meansare'provided for steering the shoveling and.' loading unit, by turning the front wheelvlband for this purpose the front vaxle a is mdunted on a turn table 3% having the `Worm wheel 85 .meshing with the worm 36 on the steering sha-tt 37 provided with the bevel gear 38 meshing with the bevel lgear 39 on the shortsha-ft 40, carrying the hanillcll. illanipul-.ition of the crank han dk` '-11 .will turn the'front wheel in the desired direction oi travel.'

rlhe operation ol3 sl'ioveling and ,loading element or unit travcling upon its own power, is simple and efticient. rl`he unit is particularly adapted to be used for loading lcars ina coal mine. i'or instance, since the cars Vmay be left sta tionary on the rails and the unit may be moved under its own power to any desired point within a room or heading, in order to scoop up the loose coal and carry it back to thc conveying element for dumping. For this purpose the scoop or shovel is4 driven into the pile and then the scoop is carried part way in a rearward direction on .the unit, until the scoop is substantially upright.

The chains are then` stopped and the unit is driven under `its own power backwardly or forwardly, as desired, and backed into prox imity to the hopper D of the conveying element at which time the dumping takes place. Theshoveling unit is then driven to another part or to the same part of the room, and another load is carried baek'to the conveying element.

A modification of the shoveling and loadthe improved unitary 'clutch member lsaid lever 5G so that the inl element is shown in F iguresl 7, 8 and 9, which is mechamcally driven by chain and sprocket connections between the electric motor j', and the rear wheels and the chain. sprockets, otherwise the construction ofthe unit is the same.A In tliehioditieation, the motor shaft is provided with a worm 42 meshing with a worm gear 4,3 on the shaft; 4.
